TV Jones has the T-90s and the T-Armonds . two very different pickups ( I can personally attest to the fact that the T-Armonds sound amazing )

from what I understand , some of the DynaSonics were made by DeArmond during that time __ and I'm guessing that some of that very special tones comes from the unpotted design . although they have their " issues " , some of the older microphonic pickups can sound other-wordly
